TPS2020DR datasheet by Texas Instruments

TPS2020DR Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the TPS2020DR can handle?
  The TPS2020DR can handle input voltages up to 40V, but it's recommended to keep it below 30V for optimal performance and reliability.
• How do I ensure the TPS2020DR is stable and doesn't oscillate?
  To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 10uF), and add a 1uF capacitor between the VIN and GND pins.
• What is the minimum input voltage required for the TPS2020DR to operate?
  The TPS2020DR can operate with input voltages as low as 2.7V, but the output voltage regulation may not be guaranteed below 3.5V.
• Can I use the TPS2020DR in a high-temperature environment?
  The TPS2020DR is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Ensure proper thermal design and heat sinking to prevent overheating.
• How do I calculate the output voltage of the TPS2020DR?
  The output voltage (VOUT) can be calculated using the formula: VOUT = 1.24V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network.
